Symptom & Impact

Mixed OpenSSL versions on FreeBSD 13 can cause application crashes or failed dependency resolution.

Environment & Reproduction

Executables fail with missing symbols or loader errors referencing incompatible libssl or libcrypto versions.

Root Cause Analysis

Ports and packages built against different SSL ABI levels or stale libraries left in custom paths.

Quick Triage

Run openssl version -a, ldd on failing binaries, and inspect /usr/local/lib for duplicate library versions.

Step-by-Step Diagnosis

Collect loader error output and current package versions before upgrades. image_ref=0

Solution – Primary Fix

Align package set with pkg upgrade, rebuild custom software against target SSL, and clear obsolete libs. image_ref=1

Solution – Alternative Approaches

Restart impacted daemons after library updates so they load corrected runtime dependencies.

Verification & Acceptance Criteria

Normalize build environment variables and avoid hard-coded legacy library search paths.

Rollback Plan

If TLS endpoints are affected, verify exposed services remain reachable after restart and cert checks.

Prevention & Hardening

Re-run failing binaries, perform TLS handshakes, and confirm no loader warnings remain.

Track ABI-sensitive upgrades and keep build toolchains pinned per environment.
